Uh...no. The i5 is superior on all accounts, and can OC higher than the G3258. The reason we suggest it is because it's like less than half the cost. The Pentium is also only a dual core which means that you can't run DSP LLE on a separate thread and if anything is running in the background it will take away from Dolphin because it has to utilize the same threads.
